Caption: Robot baby doll. Robot baby doll with part of its skin removed to show its inner workings. This toy, known as BIT (Baby IT), is a prototype of the My Real Baby interactive baby doll. The BIT doll mimics the facial expression of a human baby by changing the contours on its lifelike rubber face. The doll interacts with children by means of small sensors under the rubber skin. These sensors trigger the appropriate response according to the child's touch. For example, the doll will giggle if it is tickled. It will also request a bottle after a certain period of play. The BIT baby doll and My Real Baby were developed by IS Robotics, Sommerville, Massachusetts, USA.
